Registered Pulmonary Function Technologists

What is NBRC? The National Board for Respiratory Care (NBRC) Inc. is a non-profit organization formed in 1960 with the purpose of awarding and maintaining credentialing for Respiratory Therapists in the United States. The NBRC is the only organization in the United States which develops certification examinations for Registered R espiratory Therapists (RRTs) and Certified Respiratory Therapists (CRTs). The NBRC also offers additional specialization credentialing for respiratory practitioners that hold its certifications. The CRT and RRT designations are the standard credential in respiratory care for licensure requirements in the portions of the United States that have enacted a Respiratory Care Act. States that license respiratory therapists sometimes require the practitioner to maintain their NBRC credentialing to maintain their license to practice. The NBRC is headquartered in Olathe, Kansas. It has been in the Kansas City metropolitan area since Both the NBRC and Applied Measurement Professionals, Inc.

 Question No 2: A pulmonary function technologist is performing quality control on a nebulizer used in the 5- breath dosimeter bronchial challenge. The target output of the device is 0.09 mL, plus or minus 10%. After 10 actuations, the nebulizer output was 75μL with a 2.0 mL initial saline dose in the nebulizer. The technologist should A.

Accept the results and begin using the device. Answer: D Exams4sure.net

 Question No 3: The following results were obtained from a symptom-limited exercise (stress) test: Which of the following is true regarding these data? A. The patient is deconditioned. B. The patient has a cardiac limitation to exercise. C. The patient reached the anaerobic threshold. D. The patient has a pulmonary limitation to exercise. Answer: B Exams4sure.net

 Question No 4: When performing exercise testing on a biologic control, the measurements obtained should be compared with A. The patient population that will be tested. B. Predicted values used for the biologic control's height and weight C. Previous tests performed on the biologic control. D. At least two other biologic controls being tested. Answer: C Exams4sure.net

 Question No 5: A 12-year-old patient completed an evaluation for exercise-induced asthma in the pulmonary function laboratory. The patient completed six minutes of exercise on a treadmill with a heart rate of 145 to 150/min. The following spirometry data werecollected: A pulmonary function technologist should conclude that the exercise test is A. Inadequate workload with a positive response B. Adequate workload with a negative response C. Inadequate workload with a negative response D. Adequate workload with a positive response Answer: D Exams4sure.net

 Question No 6: The following results are obtained from an adult patient: Which of the following is the best interpretation of these values? A. Small airway disease B. Normal values C. Combined obstruction/restriction D. Airways obstruction. Answer: A Exams4sure.net

 Question No 7: Prior to an exercise study, a pulmonary function technologist finds that the patient's RER is Which of the following bestexplains this finding? A. Carbohydrate metabolism B. Protein metabolism C. Hypoventilation D. Hyperventilation Answer: D Exams4sure.net

 Question No 8: While setting up an exercise laboratory in a city with an altitude of 8,600 ft (2,775 m), a pulmonary function technologist notices the fuel cellO2analyzer is displaying 15.2%. Which of the following is the best explanation for this finding? A. This exercise system will not work at high altitude. B. The analyzer is responding to P1O2. C. F1O2decreases with increasing altitude. D. The fuel cell needs to be changed. Answer: B Exams4sure.net

 Question No 9: During daily quality control procedures on an infrared CO2analyzer, a pulmonary function technologist is unable to adjust the gain to the calibration gas concentration. Which of the following is the most likely explanation? A. Water droplets in the sample cell B. Saturation of the soda lime C. Presence of high levels of oxygen D. Increased gas sampling rate Answer: A Exams4sure.net

 Question No 10: A helium dilution test has just been performed on a patient. The following results are obtained: FRC 5.0 L VC 4.0 L ERV 1.5 L TLC was calculated to be 6.0 L by plethysmography. From this information, a pulmonary function technologist should conclude that the patient A. Had inadequate intrapulmonary mixing of inspired gas, resulting in an erroneous FRC. B. Did not perform the slow vital capacity properly, resulting in too low an FRC by helium dilution. C. Was turned into the helium dilution circuit at a lung volume considerably above FRC. D. Did not remain in the helium dilution breathing circuit long enough for equilibration. Answer: A Exams4sure.net
